I can't get a Straight Answer from Davis on Whether or Not the Weatherlink USB on a Davis Vantage Pro2 or Vue will update Data to Cumulus or Weather Underground when the Computer is Turned on in the Morning. I have an Ambient Weather 2080 currently and its worked like this for 9 years. I wanted to update my weather station and I can't believe I have to pay extra for the Data Logger Connection but now I can't even hear the Data will be stored and updated. Thanks I hope Someone will confirm. Something...

The Weatherlink connector acts as both the computer interface and a data logger. It stores data and makes it available to software like Cumulus, so that it can catch up when it hasn't been running, in a similar way to the built-in logger in your 2080.
